Complete mitochondrial genome and phylogenetic analysis of the caddisfly Neucentropus mandjuricus (Trichoptera: Polycentropodidae).

ABSTRACT: We have sequenced and annotated the complete mitogenome of Neucentropus mandjuricus Martynov, 1907, a monotypic genus of Polycentropodidae with controversial taxonomic status. The complete mitogenome of N. mandjuricus is 15,020 bp in length, including 13 protein-coding genes, two ribosomal genes, 22 transfer RNA genes, and a non-coding control region. The maximum-likelihood and Bayesian's inference trees based on 13 protein-coding genes of 23 trichopteran species show that N. mandjuricus clusters together with the other polycentropodid Plectrocnemia sp. with high support value. This study provides a basis for further study on mitogenome and phylogenetics of the Polycentropodidae.

The first mitochondrial genome for caddisfly (insecta: Trichoptera) with phylogenetic implications.

Project description:The Trichoptera (caddisflies) is a holometabolous insect order with 14,300 described species forming the second most species-rich monophyletic group of animals in freshwater. Hitherto, there is no mitochondrial genome reported of this order. Herein, we describe the complete mitochondrial (mt) genome of a caddisfly species, Eubasilissa regina (McLachlan, 1871). A phylogenomic analysis was carried out based on the mt genomic sequences of 13 mt protein coding genes (PCGs) and two rRNA genes of 24 species belonging to eight holometabolous orders. Both maximum likelihood and Bayesian inference analyses highly support the sister relationship between Trichoptera and Lepidoptera.

The complete mitochondrial genome of the North American caddisfly Anabolia bimaculata (Insecta: Trichoptera: Limnephilidae).

Project description:The caddisfly Anabolia bimaculata, is a rapidly-maturing caddisfly found in temporary ponds across western North America. Whole genome Illumina sequencing facilitated the assembly of a complete circular mitochondrial genome of 15,048 bp from A. bimaculata consisting of 78.2% AT nucleotides, 22 tRNAs, 13 protein-coding genes, two rRNAs and a control region arranged in the canonical and ancestral gene order found in insects. This gene order is consistent with the gene order found in most other caddisfly species. Maximum likelihood phylogenetic reconstruction places A. bimaculata within a monophyletic Order Trichoptera and sister to the primitive lepidopteran Micropterix calthella (Micropterigidae).

The complete mitochondrial genome of the long-horned caddisfly Triaenodes tardus (Insecta: Trichoptera: Leptoceridae).

Project description:The long-horned caddisfly Triaenodes tardus Milne, 1934 (Leptoceridae), is a widespread herbivorous North American caddisfly found in both lentic and lotic habitats. Whole genome Illumina sequencing allowed the assembly of a complete circular mitogenome of 14,963 bp from T. tardus consisting of 73.4% AT nucleotides, 22 tRNAs, 13 protein-coding genes, two rRNAs and a control region in the ancestral insect gene order. Triaenodes tardus COX1 features an atypical TTG start codon as in some lepdioptera and prokaryotes. Phylogenetic reconstruction places T. tardus as sister to Sericostoma personatum (Sericostomatidae) within a monophyletic Order Trichoptera, which is consistent with previous phylogenetic hypotheses.

The complete mitochondrial genome of the giant casemaker caddisfly Phryganea cinerea (Insecta: Trichoptera: Phryganeidae).

Project description:The rush sedge caddisfly Phryganea cinerea Walker, 1852 (Phryganeidae, the giant casemakers), is a widespread and adaptable North American caddisfly. Genome skimming by Illumina sequencing permitted the assembly of a complete 15,043 bp circular mitogenome from P. cinerea consisting of 78.2% AT nucleotides, 22 tRNAs, 13 protein-coding genes, 2 rRNAs and a control region in the ancestral insect gene order. Phryganea cinerea COX1 features an atypical CGA start codon and COX1, NAD1, NAD4, and NAD5 exhibit incomplete stop codons completed by the addition of 3' A residues to the mRNA. Phylogenetic reconstruction reveals a monophyletic Order Trichoptera and Family Phyrganeidae.

Complete mitochondrial genome of Stenopsyche tienmushanensis (Trichoptera: Stenopsychidae).

Project description:The complete mitochondrial genome (mitogenome) of Stenopsyche tienmushanensis Hwang, 1957 was assembled from Illumina high-throughput sequencing data. The circularized mitogenome has a length of 16,049 bp with a high A + T content of 77.9%, including 13 protein-coding genes (PCGs), 22 tRNA genes, and 2 rRNA genes. Its gene composition and order were the same as Stenopsyche angustata. The overall base composition is 42.0% for A, 35.9% for T, 7.6% for C, and 14.5% for G. A phylogenetic analysis based on 13 PCGs of S. tienmushanensis and 20 other caddisflies supports the placement of Stenopsychidae as sister to the Hydropsychidae within Trichoptera.

The complete mitochondrial genome of Semblis atrata (Trichoptera: Phryganeidae).

Project description:Semblis atrata is one of three Semblis species distributed in clean brooks and streams in northern Eurasia. Genomic DNA of an S. atrata sample was extracted and sequenced for assembly and annotation of its complete mitogenome. The complete mitochondrial genome of S. atrata was 14,909 bp in length and consisted of 13 protein-coding genes, 2 rRNA genes, and 22 tRNA genes. The S. atrata COX1 gene features a CGA start codon, and COX1, COX2, ND1, and ND5 exhibit incomplete stop codons that are presumed to be completed by the addition of 3' A residues to the mRNA. The nucleotide composition was highly AT biased, accounting for 77.71% of the whole mitogenome. Phylogenetic analysis placed Semblis as sister to Eubasilissa. The complete mitochondrial genome will be helpful for further studies on the population genetics of this species and phylogenetic analyses of Trichoptera.

The genome of an underwater architect, the caddisfly Stenopsyche tienmushanensis Hwang (Insecta: Trichoptera).

Project description:Caddisflies (Insecta: Trichoptera) are a highly adapted freshwater group of insects split from a common ancestor with Lepidoptera. They are the most diverse (>16,000 species) of the strictly aquatic insect orders and are widely employed as bio-indicators in water quality assessment and monitoring. Among the numerous adaptations to aquatic habitats, caddisfly larvae use silk and materials from the environment (e.g., stones, sticks, leaf matter) to build composite structures such as fixed retreats and portable cases. Understanding how caddisflies have adapted to aquatic habitats will help explain the evolution and subsequent diversification of the group. We sequenced a retreat-builder caddisfly Stenopsyche tienmushanensis Hwang and assembled a high-quality genome from both Illumina and Pacific Biosciences (PacBio) sequencing. In total, 601.2 M Illumina reads (90.2 Gb) and 16.9 M PacBio subreads (89.0 Gb) were generated. The 451.5 Mb assembled genome has a contig N50 of 1.29 M, has a longest contig of 4.76 Mb, and covers 97.65% of the 1,658 insect single-copy genes as assessed by Benchmarking Universal Single-Copy Orthologs. The genome comprises 36.76% repetitive elements. A total of 14,672 predicted protein-coding genes were identified. The genome revealed gene expansions in specific groups of the cytochrome P450 family and olfactory binding proteins, suggesting potential genomic features associated with pollutant tolerance and mate finding. In addition, the complete gene complex of the highly repetitive H-fibroin, the major protein component of caddisfly larval silk, was assembled. We report the draft genome of Stenopsyche tienmushanensis, the highest-quality caddisfly genome so far. The genome information will be an important resource for the study of caddisflies and may shed light on the evolution of aquatic insects.

Twenty-four new species of Polycentropus (Trichoptera, Polycentropodidae) from Brazil.

Project description:Twenty-four new species of the caddisfly genus Polycentropus (Insecta: Trichoptera: Polycentropodidae) occurring in Brazil are diagnosed, described, and the male genitalia of each are illustrated. Eighteen of the new species are placed in the Polycentropus jorgenseni species complex of the Polycentropus gertschi group of New World Polycentropussensu lato. Furthermore, 6 new species within the Polycentropus gertschi group (Polycentropus ancistrussp. n., Polycentropus boraceiasp. n., Polycentropus cariocasp. n., Polycentropus froehlichisp. n., Polycentropus galharadasp. n., and Polycentropus graciosasp. n.) are placed in an informal diagnostic cluster of species with Polycentropus urubici Holzenthal and Almeida. Ten of the other Polycentropus gertschi group species form a second cluster of diagnostically similar species, the Polycentropus soniae cluster (Polycentropus caaetesp. n., Polycentropus carolaesp. n., Polycentropus cheliceratussp. n., Polycentropus fluminensissp. n., Polycentropus itatiaiasp. n., Polycentropus minerosp. n., Polycentropus santateresaesp. n., Polycentropus soniaesp. n., Polycentropus tripuisp. n., and Polycentropus virginiaesp. n.). Two of the remaining 8 new species are included in the Polycentropus jorgenseni species complex (Polycentropus cipoensissp. n. and Polycentropus verruculussp. n.), while the remaining 6 are unique and cannot be placed in one of the groups at this time (Polycentropus acinaciformissp. n., Polycentropus amphirhamphussp. n., Polycentropus cachoeirasp. n., Polycentropus inusitatussp. n., Polycentropus paprockiisp. n. and Polycentropus rosalysaesp. n.).
